So, I have read NOT to use an electric blanket/mattress pad while temping and I understand why, sortof... so my question is, can you use some sort of bed heating device if you start at the beginning of your cycle, so you are starting the cycle with already slightly elevated temps? Will you still see the shifts, but maybe at a higher temp than what previous cycles were? Or does it completely screw with the temps?

Good question! I guess it would depend partly on whether it was always on the same level and if you left it on for the same amount of time each day. I love my electric mattress warmer but it hasn't made its way out if the closet yet.

Thanks ladies! That is pretty much what common sense was telling me, but then I read to NEVER use an electric blanket/mattress pad when temping. I kept thinking that if I started at the beginning of my cycle and kept it at the same level it shouldn't matter, but needed some confirmation from others! THANK YOU SO MUCH!!
